Boko Haram

Before it was colonized and subsequently incorporated into British Empire in 1900 as Colonial Nigeria, the Bornu Empire ruled the territory where Boko Haram is currently active. It was a sovereign sultanate run according to the principles of the Constitution of Medina, with a majority Kanuri Muslim population. In 1903, both the Borno Emirate and Sokoto Caliphate had come under British rule. Christian missionaries at this time spread the Christian message in the region and had many converts among the Nigerian populace.[67] British rule ended when Nigeria was granted independence in 1960.[68][69]

Except for a brief period of civilian rule between 1979 and 1983, Nigeria was governed by a series of military dictatorships from 1966 until the advent of democracy in 1999. Ethnic militancy is thought to have been one of the causes of the 1967–1970 civil war; religious violence reached a new height in 1980 in Kano, the largest city in the north of the country, where the Muslim fundamentalist sect Yan Tatsine ("followers of Maitatsine") instigated riots that resulted in four or five thousand deaths. In the ensuing military crackdown, Maitatsine was killed, fuelling a backlash of increased violence that spread across other northern cities over the next twenty years.[70] Social inequality and poverty contributed both to the Maitatsine and Boko Haram uprisings.[58]^:97–98

In the decades since the end of British rule, politicians and academics from the mainly Islamic North have expressed their fundamental opposition to Western education. Political ethno-religious interest groups, whose membership includes influential political, military and religious leaders, have thrived in Nigeria, though they were largely suppressed under military rule. Their paramilitary wings, formed since the country's return to civilian rule, have been implicated in much of the sectarian violence in the years following. The Arewa People's Congress, the militia wing of the Arewa Consultative Forum, the main political group representing the interests of northern Nigeria, is a well-funded group with military and intelligence expertise, and is considered capable of engaging in military action, including covert bombing.[71]

Mohammed Yusuf founded the sect that became known as Boko Haram in 2002 in Maiduguri, the capital of the north-eastern state of Borno. He established a religious complex and school that attracted poor Muslim families from across Nigeria and neighbouring countries. The center had the political goal of creating an Islamic state, and became a recruiting ground for jihadis. By denouncing the police and state corruption, Yusuf attracted followers from unemployed youth.[48][68][72][73] He is reported to have used the existing infrastructure in Borno of the Izala Society (Jama'at Izalatil Bidiawa Iqamatus Sunnah), a popular conservative Islamic sect, to recruit members, before breaking away to form his own faction. The Izala were originally welcomed into government, along with people sympathetic to Yusuf. Boko Haram conducted its operations more or less peacefully during the first seven years of its existence, withdrawing from society into remote north-eastern areas. The government repeatedly ignored warnings about the increasingly militant character of the organization.[49][74] The Council of Ulama advised the government and the Nigerian Television Authority not to broadcast Yusuf's preaching, but their warnings were ignored. Yusuf's arrest elevated him to hero status. Borno's Deputy Governor Alhaji Dibal has reportedly claimed that al-Qaeda had ties with Boko Haram, but broke them when they decided that Yusuf was an unreliable person.[44] Stephen Davis, a former Anglican clergyman who has negotiated with Boko Haram many times blames local Nigerian politicians who support local bandits like Boko Haram in order for them to make life difficult for their political opponents. In particular Davis has blamed the former governor of Borno State Ali Modu Sheriff, who initially supported Boko Haram, but no longer needed them after the 2007 elections and stopped funding them. Sheriff denies the accusations.[75]

In 2015 West African offensive, Boko Haram lost most of the territory it had occupied over time and retreated to the Sambisa Forest. Boko Haram retreated to guerilla warfare tactics. But since 2018, there has been major spike in attacks by Boko Haram. Majority of these attacks are concentrated to Borno State. Attacks by Boko Haram resulted in over seventeen hundred fatalities in first half of 2019, including casualties of its own members.[38] The terrorist organization has been able to recruit in large numbers from climate change induced poverty and violence struck Lake Chad basin by offering small loans[76] and promising big rewards.[77] It also continues to kidnap and force young boys to join them.[78] Boko Haram is better equipped with drones, weapons and vehicles captured from and sometimes abandoned by Nigerian military during ambush.[37] To better fortify itself, Nigerian military has concentrated rural population in its garrison towns. This has allowed Boko Haram to rein freely in countryside. In 2019, they are believed to be back in control of 4 out of 10 zones of Bono State.[37]

Map of Nigeria from the CIA World Factbook

In 2008, police began an investigation into the group code-named Operation Flush. On 26 July, security forces arrested nine Boko Haram members and confiscated weapons and bomb-making equipment. Either this or a clash with police during a funeral procession led to revenge attacks on police and widespread rioting in Bauchi, Maiduguri, Potiskum and Wudil. A joint military task force operation was launched in response. By 30 July more than 700 people had been killed; police stations, prisons, government offices, schools and churches had been destroyed.[25][58]^:98–102[81][82] Yusuf was arrested, and died in custody "while trying to escape". As had been the case decades earlier in the wake of the 1980 Kano riots, the killing of the leader of an extremist group would have unintended consequences. He was succeeded by Abubakar Shekau, formerly his second-in-command.[83][84] A classified cable apparently sent from the U.S. Embassy in Abuja in November 2009, has been published on WikiLeaks:[44]

[Borno political and religious leaders] ... asserted that the state and federal government responded appropriately and, apart from the opposition party, overwhelmingly supported Yusuf's death without misgivings over the extrajudicial killing. Security remained a concern in Borno, with residents expressing concern about importation of arms and exchanges of religious messages across porous international borders.

According to the leaked document, there were reports that Yusuf's deputy had survived, and audio tapes were believed to be in circulation in which Boko Haram threatened future attacks. Nevertheless, many observers did not anticipate imminent bloodshed. Security in Borno was downgraded. Borno government official Alhaji Boguma believed that the state deserved praise from the international community for ending the conflict in such a short time, and that the "wave of fundamentalism" had been "crushed".[44]

On 7 September 2010, having regrouped under their new leader, Boko Haram broke 105 of its members out of prison in Bauchi along with over 600 other prisoners. The group went on to intensify their insurgency, launching many attacks in Nigeria, mostly in the north of the country.[70][85][86]

On 24 December 2010, Boko Haram exploded four bombs in Jos and attacks two churches in Maiduguri.[87]

On 31 December 2010, Boko Haram bombed a barracks in Abuja, killing four civilians.

Under Shekau's leadership, the group continuously improved its operational capabilities. It launched a string of IED attacks against soft targets and its first vehicle-borne IED attack on 16 June 2011, killing six at Abuja's police headquarters. On 26 August, Boko Haram bombed the United Nations (UN) headquarters in Abuja, the first time they had struck a Western target. A spokesman claiming responsibility for the attack, in which 11 UN staff members died as well as 12 others, with more than 100 injured, warned of future planned attacks on U.S. and Nigerian government interests. Speaking soon after the U.S. embassy's announcement of the arrival in the country of the FBI, he went on to announce Boko Haram's terms for negotiation, i.e. the release of all imprisoned members. The increased sophistication of the group led observers to speculate that Boko Haram was affiliated with Al-Qaeda in the Islamic Maghreb (AQIM), which was active in Niger.[85][86][88][89][90][91][92]

Boko Haram has maintained a steady rate of attacks since 2011, striking a wide range of targets, multiple times per week. They have attacked politicians, religious leaders, security forces and civilian targets. The tactic of suicide bombing, used in the two attacks in the capital - on the police and UN headquarters - was new to Nigeria. In Africa as a whole, it had only been used by al-Shabaab in Somalia and to a lesser extent AQIM.[7][25][89][93][94][95]

Within hours of Goodluck Jonathan's presidential inauguration in May 2011, Boko Haram carried out a series of bombings in Bauchi, Zaria and Abuja. The most successful of these was the attack on the army barracks in Bauchi. A spokesman for the group told BBC Hausa that the attack had been carried out, as a test of loyalty, by serving members of the military hoping to join the group. This charge was later refuted by an army spokesman who claimed: "This is not a banana republic". However, on 8 January 2012 the president would announce that Boko Haram had in reality infiltrated both the army and the police, as well as the executive, parliamentary and legislative branches of government. Boko Haram's spokesman also claimed responsibility for the killing outside his home in Maiduguri of the politician Abba Anas Ibn Umar Garbai, the younger brother of the Shehu of Borno, who was the second most prominent Muslim in the country after the Sultan of Sokoto. He added: "We are doing what we are doing to fight injustice, if they stop their satanic ways of doing things and the injustices, we would stop what we are doing".[96][97]

This was one of several political and religious assassinations Boko Haram carried out that year, with the presumed intention of correcting injustices in the group's home state of Borno. Meanwhile, the trail of massacres continued relentlessly, apparently leading the country towards civil war. By the end of 2011, these conflicting strategies led observers to question the group's cohesion; comparisons were drawn with the diverse motivations of the militant factions of the oil-rich Niger Delta. Adding to the confusion, in November the State Security Service announced that four criminal syndicates were operating under the name Boko Haram.[93][98][99][100]

The common theme throughout the north-east was the targeting of police, who were regularly massacred at work or in drive-by shootings at their homes, either in revenge for the killing of Yusuf, or as representatives of the state apparatus, or for no particular reason. Five officers were arrested for Yusuf's murder, which had no noticeable effect on the level of unrest. Opportunities for criminal enterprise flourished. Hundreds of police were dead and more than 60 police stations had been attacked by mid-2012. The government's response to this self-reinforcing trend towards insecurity was to invest heavily in security equipment, spending $5.5 billion, 20 percent of their overall budget, on bomb detection units, communications and transport; and $470 million on a Chinese CCTV system for Abuja, which has failed in its purpose of detecting or deterring acts of terror.[99][101][102][103][104][105]

The election defeat of former military dictator Muhammadu Buhari increased ethno-religious political tensions, as it broke the terms of a tacit agreement that the presidency would alternate after two terms of office between candidates from the Christian south and Muslim north of the country. Sectarian riots engulfed the twelve northern states of the country during the three days following the election, leaving more than 800 dead and 65,000 displaced. The subsequent campaign of violence by Boko Haram culminated in a string of bombings across the country on Christmas Day. In the outskirts of Abuja, 37 died in a church that had its roof blown off. One resident commented, "Cars were in flames and bodies littered everywhere", a phrase commonly repeated in international press reports about the bombings. Similar Christmas events had been reported in previous years. Jonathan declared a state of emergency on New Year's Eve in local government areas of Jos, Borno, Yobe and Niger and closed the international border in the north-east.[106][107][108][109][110][111][112][113][114][115]

Three days later they began a series of mostly small-scale attacks on Christians and members of the Igbo ethnic group, causing hundreds to flee. In Kano, on 20 January, they carried out by far their most deadly action yet, an assault on police buildings, killing 190. One of the victims was a TV reporter. The attacks included a combined use of car bombs, suicide bombers and IEDs, supported by uniformed gunmen.[47][116][117][118][119][120][121]

Amnesty International and Human Rights Watch published reports in 2012 that were widely quoted by government agencies and the media, based on research conducted over the course of the conflict in the worst affected areas of the country. The NGOs were critical of both security forces and Boko Haram. HRW stated "Boko Haram should immediately cease all attacks, and threats of attacks, that cause loss of life, injury, and destruction of property. The Nigerian government should take urgent measures to address the human rights abuses that have helped fuel the violent militancy". According to the 2012 US Department of State Country Report on Human Rights Practices:[32]

[S]erious human rights problems included extrajudicial killings by security forces, including summary executions; security force torture, rape, and other cruel, inhuman, or degrading treatment of prisoners, detainees, and criminal suspects; harsh and life-threatening prison and detention center conditions; arbitrary arrest and detention; prolonged pretrial detention; denial of fair public trial; executive influence on the judiciary; infringements on citizens' privacy rights; restrictions on freedom of speech, press, assembly, religion, and movement.

On 9 October, witnesses in Maiduguri claimed members of the JTF "Restore Order" [a vigilante group], based in Maiduguri, went on a killing spree after a suspected Boko Haram bomb killed an officer. Media reported the JTF killed 20 to 45 civilians and razed 50 to 100 houses in the neighborhood. The JTF commander in Maiduguri denied the allegations. On 2 November, witnesses claimed the JTF shot and killed up to 40 people during raids in Maiduguri. The army claimed it dismissed some officers from the military as a result of alleged abuses committed in Maiduguri, but there were no known formal prosecutions in Maiduguri by year's end.

Credible reports also indicated ... uniformed military personnel and paramilitary mobile police carried out summary executions, assaults, torture, and other abuses throughout Bauchi, Borno, Kano, Kaduna, Plateau, and Yobe states ... The national police, army, and other security forces committed extrajudicial killings and used lethal and excessive force to apprehend criminals and suspects, as well as to disperse protesters. Authorities generally did not hold police accountable for the use of excessive or deadly force or for the deaths of persons in custody. Security forces generally operated with impunity in the illegal apprehension, detention, and sometimes extrajudicial execution of criminal suspects. The reports of state or federal panels of inquiry investigating suspicious deaths remained unpublished.

There were no new developments in the case of five police officers accused of executing Muhammad Yusuf in 2009 at a state police headquarters. In July 2011 authorities arraigned five police officers in the federal high court in Abuja for the murder of Yusuf. The court granted bail to four of the officers, while one remained in custody.

Police use of excessive force, including use of live ammunition, to disperse demonstrators resulted in numerous killings during the year. For example, although the January fuel subsidy demonstrations generally remained peaceful, security forces reportedly fired on protesters in various states across the country during those demonstrations, resulting in 10 to 15 deaths and an unknown number of wounded.

Despite some improvements resulting from the closure of police checkpoints in many parts of the country, states with an increased security presence due to the activities of Boko Haram experienced a rise in violence and lethal force at police and military roadblocks.

Continuing abductions of civilians by criminal groups occurred in the Niger Delta and Southeast ... Police and other security forces were often implicated in the kidnapping schemes.

Although the constitution and law prohibit such practices and provide for punishment of such abuses, torture is not criminalized, and security service personnel, including police, military, and State Security Service (SSS) officers, regularly tortured, beat, and abused demonstrators, criminal suspects, detainees, and convicted prisoners. Police mistreated civilians to extort money. The law prohibits the introduction into trials of evidence and confessions obtained through torture; however, police often used torture to extract confessions.[122]

Lake Chad

Nigeria's Borno State, where Boko Haram is based, adjoins Lake Chad as do Niger, Cameroon and the country of Chad. The conflict and refugees spilled over the national borders to involve all four countries.

In 2013, Boko Haram increased operations in Northern Cameroon, and were involved in skirmishes along the borders of Chad and Niger. They were linked to a number of kidnappings, often reportedly in association with the splinter group Ansaru, drawing towards them a higher level of international attention.

The U.S. Bureau of Counterterrorism provides the following summary of Boko Haram's 2013 foreign operations:

In February 2013, Boko Haram was responsible for kidnapping seven French tourists in the far north of Cameroon. In November 2013, Boko Haram members kidnapped a French priest in Cameroon. In December 2013, Boko Haram gunmen reportedly attacked civilians in several areas of northern Cameroon. Security forces from Chad and Niger also reportedly partook in skirmishes against suspected Boko Haram members along Nigeria's borders. In 2013, the group also kidnapped eight French citizens in northern Cameroon and obtained ransom payments for their release.[7]

Boko Haram has often managed to evade the Nigerian army by retreating into the hills around the border with Cameroon, whose army is apparently unwilling to confront them. Nigeria, Chad and Niger had formed a Multinational Joint Task Force in 1998. In February 2012, Cameroon signed an agreement with Nigeria to establish a Joint Trans-Border Security Committee, which was inaugurated in November 2013, when Cameroon announced plans to conduct "coordinated but separate" border patrols in 2014. It convened again in July 2014 to further improve cooperation between the two countries.[123][124][125][126][127]

In late 2013, Amnesty International received 'credible' information that over 950 inmates had died in custody, mostly in detention centres in Maiduguri and Damaturu, within the first half of the year. Official state corruption was also documented in December 2013 by the UK Home Office:[128][129]

The NPF [Nigeria Police Force], SSS, and military report to civilian authorities; however, these security services periodically act outside of civilian control. The government lack effective mechanisms to investigate and punish abuse and corruption. The NPF remain susceptible to corruption, commit human rights abuses, and generally operate with impunity in the apprehension, illegal detention, and sometimes execution of criminal suspects. The SSS also commit human rights abuses, particularly in restricting freedom of speech and press. In some cases private citizens or the government brought charges against perpetrators of human rights abuses in these units. However, most cases lingered in court or went unresolved after an initial investigation.

The state of emergency was extended in May 2013 to cover the whole of the three north-eastern states of Borno, Adamawa and Yobe, raising tensions in the region. In the 12 months following the announcement, 250,000 fled the three states, followed by a further 180,000 between May and August 2014. A further 210,000 fled from bordering states, bringing the total displaced by the conflict to 650,000. Many thousands left the country. An August 2014 Amnesty International video showed Army and allied militia executing people, including by slitting their throats, and dumping their corpses in mass graves.[130][131][132] According to Human Rights Watch, more than 130 villages and towns were attacked or controlled by the group.[133]

On 11 August 2013, BH killed 44 people in a mass shooting at a mosque in Konduga, Borno State.[134]

A car bombing in Maiduguri on 14 January killed at least 17 people.[135]

Michelle Obama raising public awareness of the Chibok kidnapping

In April, Boko Haram kidnapped 276 schoolgirls from Chibok. Shekau announced his intention of selling them into slavery. More than 50 escaped. The incident brought Boko Haram extended global media attention, much of it focused on the pronouncements of the U.S. Former First Lady Michelle Obama[136] Faced with condemnation for his perceived incompetence, as well as allegations from Amnesty International of state collusion, President Jonathan responded by hiring a Washington PR firm.[137][138][139][140][141][142][143][144]

Parents of the missing girls and those who had escaped were kept waiting until July to meet with the president, which caused them concern. In October, the government announced the girls' imminent release, but the information proved unreliable. The announcement to the media of a peace agreement and the imminent release of all the missing girls was followed days later by a video message in which Shekau stated that no such meeting had taken place and that the girls had been "married off". The announcement to the media, unaccompanied by any evidence of the reality of the agreement, was thought by analysts to have been a political ploy by the president to raise his popularity before his confirmation of his candidacy in the 2015 general election. Earlier in the year, the girls' plight had featured on "#BringBackOurGirls" political campaign posters in the streets of the capital, which the president denied knowledge of and soon took down after news of criticism surfaced. These posters, which were interpreted, to the dismay of campaigners for the girls' recapture, as being designed to benefit from the fame of the kidnapping, had also been part of Jonathan's "pre-presidential campaign". In September, "#BringBackGoodluck2015" campaign posters again drew criticism.[145] The official announcement of the president's candidacy was made before cheering crowds in Abuja on 11 November.[146]

In February 2016, the organizations International Alert and UNICEF published a study revealing that girls and women released from Boko Haram captivity often face rejection upon returning to their communities and families, in part due to a culture of stigma around sexual violence.[147]

Northern Cameroon

Boko Haram continued to increase its presence in northern Cameroon. On 16 May, ten Chinese workers were abducted in a raid on a construction company camp in Waza, near the Nigerian border. Vehicles and explosives were also taken in the raid, and one Cameroonian soldier was killed. Cameroon's anti-terrorist Rapid Intervention Battalion attempted to intervene but were vastly outnumbered.[148] In July, the deputy prime minister's home village was attacked by around 200 militants; his wife was kidnapped, along with the Sultan of Kolofata and his family. At least 15 people, including soldiers and police, were killed in the raid. The deputy prime minister's wife was subsequently released in October, along with 26 others including the ten Chinese construction workers who had been captured in May; authorities made no comment about any ransom, which the Cameroon government had previously claimed it never pays.[149] In a separate attack, nine bus passengers and a soldier were shot dead and the son of a local chief was kidnapped. Hundreds of local youths are suspected to have been recruited. In August, the remote Nigerian border town of Gwoza was overrun and held by the group. In response to the increased militant activity, the Cameroonian president sacked two senior military officers and sent his army chief with 1000 reinforcements to the northern border region.[150][151][152]

Between May and July 2014, 8,000 Nigerian refugees arrived in the country, up to 25 percent suffering from acute malnutrition. Cameroon, which ranked 150 out of 186 on the 2012 UNDP HDI, hosted as of August 2014 107,000 refugees fleeing unrest in the CAR, a number that was expected to increase to 180,000 by the end of the year.[153][154][155] A further 11,000 Nigerian refugees crossed the border into Cameroon and Chad during August.[156]

Wounded people following a bomb attack by Boko Haram in Nyanya, in April 2014

The attack on Gwoza signalled a change in strategy for Boko Haram, as the group continued to capture territory in north-eastern and eastern areas of Borno, as well as in Adamawa and Yobe. Attacks across the border were repelled by the Cameroon military.[157] The territorial gains were officially denied by the Nigerian military. In a video obtained by the news agency AFP on 24 August, Shekau announced that Gwoza was now part of an Islamic caliphate.[158] The town of Bama, 70 kilometres (45 mi) from the state capital Maiduguri, was reported to have been captured at the beginning of September, resulting in thousands of residents fleeing to Maiduguri, even as residents there were themselves attempting to flee.[159] The military continued to deny Boko Haram's territorial gains, which were, however, confirmed by local vigilantes who had managed to escape. The militants were reportedly killing men and teenage boys in the town of over 250,000 inhabitants. Soldiers refused orders to advance on the occupied town; hundreds fled across the border into Cameroon, but were promptly repatriated. Fifty-four deserters were later sentenced to death by firing squad.[160][161]

On 17 October, the Chief of the Defence Staff announced that a ceasefire had been brokered, stating: "I have accordingly directed the service chiefs to ensure immediate compliance with this development in the field". Despite a lack of confirmation from the militants, the announcement was publicised in newspaper headlines worldwide. However, within 48 hours the same publications were reporting that Boko Haram attacks had continued unabated. It was reported that factionalisation would make such a deal particularly difficult to achieve.[162][163][164]

Location of the town of Mubi within Adamawa State

On 29 October, Mubi, a town of 200,000 in Adamawa, fell to the militants, further undermining confidence in the peace talks. Thousands fled south to Adamawa's capital city, Yola.[165] Amid media speculation that the ceasefire announcement had been part of President Jonathan's re-election campaign, a video statement released by Boko Haram through the normal communication channels via AFP on 31 October stated that no negotiations had in fact taken place.[166][167] Mubi was said to have been recaptured by the army on 13 November. On the same day, Boko Haram seized Chibok, but two days later the army recaptured the largely deserted town. As of 16 November it was estimated that more than twenty towns and villages had been taken control of by the militants.[168][169] On 28 November, 120 died in an attack at the central mosque in Kano during Friday prayers. There were 27 Boko Haram attacks during the month of November, killing at least 786.[170][171]

On 3 December, it was reported that several towns in North Adamawa had been recovered by the Nigerian military with the help of local vigilantes and Bala Nggilari, the governor of Adamawa state, said that the military were aiming to recruit 4,000 vigilantes.[172] On 13 December, Boko Haram attacked the village of Gumsuri in Borno, killing over 30 and kidnapping over 100 women and children.[161]

In the second half of December, the focus of activity switched to the Far North Region of Cameroon, beginning on the morning of 17 December when an army convoy was attacked with an IED and ambushed by hundreds of militants near the border town of Amchide, 60 kilometres (40 mi) north of the state capital Maroua. One soldier was confirmed dead, and an estimated 116 militants were killed in the attack, which was followed by another attack overnight with unknown casualties.[173] On 22 December, the Rapid Intervention Battalion followed up with an attack on a Boko Haram training camp near Guirdivig, arresting 45 militants and seizing 84 children aged 7–15 who were undergoing training, according to a statement from Cameroon's Ministry of Defense. The militants fled in pick-up trucks carrying an unknown number of their dead; no information on army casualties was released.[174] On 27–28 December, five villages were simultaneously attacked, and for the first time the Cameroon military launched air attacks when Boko Haram briefly occupied an army camp. Casualty figures were not released. According to Information Minister Issa Tchiroma:

Units of the group attacked Makari, Amchide, Limani and Achigachia in a change of strategy which consists of distracting Cameroonian troops on different fronts, making them more vulnerable in the face of the mobility and unpredictability of their attacks.[175]

On 3 January, Boko Haram attacked Baga, seizing it and the multinational joint task force military base. As the militants advanced the army fled. Some residents managed to escape to Chad.[176] Although the death toll of the massacre was earlier estimated by Western media to be upwards of 2000,[177] the Defence Ministry dismissed these claims as "speculation and conjecture", estimating the figure to be closer to 150.[178] On 25 January, the militants advanced to Monguno, capturing the town and a nearby military base. Their advance on Maiduguri and Konduga, 40 km to the southeast, was repelled. After retaking Monguno, the army expelled the militants from Baga on 21 February.[179]

The Baga massacre was one of the Nigerian army's biggest defeats in terms of loss of equipment and civilian casualties. Several officers were court-martialed. In October, General Enitan Ransome-Kuti was dismissed from the army and sentenced to six months imprisonment. It was determined that he had failed in his duty to launch a counter-attack after retreating from the town.[180]

Map of Boko Haram's territorial control on 10 April 2015, over 2 months after the start of the 2015 West African offensive

Starting in late January, a coalition of military forces from Nigeria, Chad, Cameroon, and Niger began a campaign against Boko Haram.[181] On 4 February, the Chad Army killed over 200 Boko Haram militants.[182] Soon afterwards, Boko Haram launched an attack on the Cameroonian town of Fotokol, killing 81 civilians, 13 Chadian soldiers and 6 Cameroonian soldiers.[183]

On 7 March, Boko Haram's leader Abubakar Shekau pledged allegiance to ISIL via an audio message posted on the organisation's Twitter account.[34][18] Nigerian army spokesperson Sami Usman Kukasheka said the pledge was a sign of weakness and that Shekau was like a "drowning man".[184] On 12 March 2015, ISIL's spokesman Abu Mohammad al-Adnani released an audiotape in which he welcomed the pledge of allegiance, and described it as an expansion of the group's caliphate to West Africa.[17]

On 24 March, residents of Damasak, Nigeria said that Boko Haram had taken more than 400 women and children from the town as they fled from coalition forces who retook it and discovered a mass grave of Boko Haram victims.[185] On 27 March, the Nigerian Army captured Gwoza, which was believed to be the location of Boko Haram headquarters.[186] On election day 28 March 2015, Boko Haram extremists killed 41 people, including a legislator, to discourage hundreds from voting.[187]

In March, Boko Haram lost control of the Northern Nigerian towns of Bama[188] and Gwoza[189] to the Nigerian army. The Nigerian authorities said that they had taken back 11 of the 14 districts previously controlled by Boko Haram.[188] In April, four Boko Haram camps in the Sambisa Forest were overrun by the Nigerian military who freed nearly 300 females.[190] Boko Haram forces were believed to have retreated to the Mandara Mountains, along the Nigeria-Cameroon border.[191]

In late February, suicide bombers killed over 30 people in Potiskum and Kano.

A report by the Catholic diocese of Maiduguri estimated that as of May 2015 over 5,000 Nigerian Catholics had been killed by Boko Haram. The diocese also reported 7,000 widows and 10,000 orphans among its laity. Furthermore, Boko Haram militants had taken over several parish centres within the diocese.[192]

On 15 June, two suicide bombings of police sites in N'Djamena, the capital and largest city of Chad, killed 38 people. Boko Haram later claimed responsibility for these attacks.[193] On 27 June, suicide bombers killed six members of their own cell and five police officers during a police raid.[194] On 11 July, a male suicide bomber disguised in a woman's burqa detonated his explosives belt in the main market of N'Djamena, next to the main mosque, killing 15 people and injuring 80.[195] Several days after the bombing, Boko Haram claimed responsibility via Twitter, signing as "Islamic State, West Africa province".[196]

Boko Haram militants attacked multiple mosques between 1 and 2 July. Forty-eight men and boys were killed on the 1st at one mosque in Kukawa. Seventeen were wounded in the attack. Ninety-seven others, mostly men, were killed in numerous mosques on the 2nd with a number of women and young girls killed in their homes. An unknown number were wounded.[197]

On 5 July, major attacks occurred in Potiskum, Jos and Borno State.[198]

The March 2015 general election was won by Buhari, who had vowed to remove inefficiency and corruption in the military.[199] On 9 September 2015, the Director of Information at the Defence Headquarters, Colonel Rabe Abubakar announced that all known Boko Haram camps and cells had been destroyed, and that the group was so weakened that they could no longer hold any territory:

These terrorists have been subdued, even if they are adopting other means and as they are re-strategising, we are also doing the same and pre-empting them. We have coordinated the air and ground assaults to make sure that these terrorists' hideouts are completely decimated. As I am speaking to you, all the terrorists' camps have completely been wiped out. So right now they are completely in disarray, have no command and control of where to plan. We have even taken over their camps that most of them abandoned and are attempting to blend into towns and communities. We have also apprehended some of them and very soon innocent Nigerians can move back to their communities. We are making a lot of headway, so people should know that Boko Haram is no longer strong enough to hold grounds. Very soon this issue of whether they are in control of any territory in Nigeria or not will come to the open. I am assuring you that they will never again recapture the territory taken from them because what is happening right now with the deployment of troops, equipment and morale will ensure that.[36][200]

Buhari later reiterated in December that Boko Haram was "technically defeated"[201] and declared in December 2016 that the group had been entirely ousted from its last stronghold of Sambisa Forest.[202]

On 20 September, a series of bombings occurred in Maiduguri and Monguno and the attacks followed an announcement by Shekau refuting the army's claims of defeat. A military spokesman stated that the event showed the "high level of desperation" of Boko Haram.[203] The Arewa Consultative Forum released a statement condemning the bombings and commending the military offensive:

The ACF condemns in strong terms the continued use of suicide bombers by Boko Haram terrorists to kill innocent people in the name of a religious war, as no religion condones such cruel and barbaric act. The ACF wishes to commend the military and other security agencies for the continued onslaught on the terrorists' enclaves and hideouts, thereby dislodging them from their strong holds. The ACF urges the military not to be deterred by the cowardly act of the Boko Haram terrorists, as their renewed effort and determination will soon end the insurgency. The ACF also appeals to the military to intensify its synergy of sharing intelligence with the community.[204]

The village borders Cameroon and the Sambisa forest.[217] On 18 October the village of Dar, Adamawe was attacked. Maina Ularamu, a former Chairman of Madagali Local Government Area, stated: "A large number of gunmen invaded the village, forcing residents to flee to a nearby bush.

One army commander later died of his wounds.[230] On 12 October, the first 90 of a proposed deployment of 300 US troops arrived in the region to assist with training, reconnaissance and airborne intelligence using Predator drones.[231] On 16 October, more than six security vehicles were transferred to the Cameroon military. An AFRICOM spokesman said that increased cooperation had led them "to study the viability of ISR flights from a temporary location in Cameroon". The deployment is "totally separate and distinct" from operations in Chad and Niger, where 250 and 85 personnel, respectively, are conducting missions including ISR and training.[232]

On 23 October, Boko Haram fighters were driven out of Kerawa, a village of 50,000 in Kolofata, a commune in the far north region. They had briefly occupied the village until the arrival of security forces. Reports of civilian casualties ranged from eight to eleven.

On 2 December, Cameroon's Defense Minister claimed that, at the end of November, 100 Boko Haram members had been killed and 900 hostages freed, and that a large stockpile of arms and munitions, and black-and-white ISIL flags had been seized.[240] Information Minister Issa Tchiroma Bakari said that "[t]he people that were freed are just villagers. The [Chibok] schoolgirls who are missing are not amongst the group".[241]

On 6 October, the Chadian Army reported an attack in the border region of Lake Chad. 11 soldiers were killed and 14 wounded in the pre dawn cross-border infiltration, and 17 militants were also killed, according to an army spokesman.[242] On 10 October, 5 suicide bombers killed 33 in the market in Baga Sola, a camp for Nigerian refugees.[243] On 1 November, two dawn attacks on army posts occurred. Eleven militants and two soldiers were killed at Kaika, and in an attempted suicide bombing at Bougouma, "Two members of Boko Haram were neutralised and a third blew himself up, wounding 11 civilians", according to a government statement.[244][245] A state of emergency was imposed in the western Lake Chad region on 9 November, initially for 12 days, but extended by Chad's national assembly on 18 November to four months.[246]

On 5 December, three female suicide bombers killed about 30 at a crowded market on the island of Koulfoua in Lake Chad.[247]

On 25 September, at least 15 civilians were massacred and stores were looted in a cross-border raid on a Niger village, according to anonymous military sources.[248] On 2 October two soldiers died and four were wounded in a Boko Haram attack on a village near the Nigerian border in Niger's Diffa province. The militants also looted stores, according to Niger army officers. On 4 October, according to an aid worker, a policeman and five civilians were killed by 4 suicide bombers near the Nigerian border. On 6 October, three suspected Boko Haram militants accidentally blew themselves up while transporting explosives to Bosso town in Diffa. On 21 October, near Diffa town, two soldiers were killed by explosives while intercepting an attack. Diffa region hosts over 150,000 Nigerian refugees. It is under a state of emergency. On 14 October a curfew and movement restrictions were imposed.[249] At least 57 attacks occurred there from February to October. More than 1,100 Boko Haram suspects were arrested in Niger during 2015.[250][251][252]

On 11 November, two Niger military officials described an attack on a village in Bosso district in which five civilians and 20 militants were killed. A senior government official later denied that the attack had occurred, according to Reuters.[253][254] On 26 November, Boko Haram launched a cross-border night raid on Wogom village in Diffa province. A government spokesman, Justice Minister Marou Amadou stated: "Eighteen villagers were killed, including the chief imam for the village whose throat was slit by his own nephew".[255][256] On 13 March 2018, the United Nations Special Rapporteur on the human rights of internally displaced persons (IDP), Cecilia Jimenez-Damary said "Since the first attacks in Niger by Boko Haram in 2015, the Diffa region, in the south-eastern part of the country, has been confronted with a continuing security crisis which has uprooted more than 129,000 internally from their homes, in addition to the arrival of 108,000 refugees from Nigeria, and has triggered a humanitarian crisis.[257] He said that IDPs in Niger are posing huge challenges to the country and "require a strong and comprehensive response". He also said situation in the regions bordering Mali has led to the displacement of some 1,540 persons.

On 25 January, over 30 people were killed in a quadruple suicide bombing in Bodo, Far North Region, Cameroon.[258]

On 30 January, at least 86 people were killed and at least 62 more injured in an attack by Boko Haram militants on Dalori Village which is located 4 kilometers from Maiduguri, Nigeria.[259] The Nigerian Army was unable to fight the militants until reinforcements arrived, causing Boko Haram to retreat.[260]

Johns Hopkins University figures indicated that Boko Haram killed 244 people in the second quarter – the lowest quarterly figure for five years.[261]

In early August, ISIL announced that it had appointed Abu-Musab al-Barnawi as the new leader of the group.[262] In a video released a few days later, Shekau refused to accept al-Barnawi's appointment as leader and vowed to fight him while stating that he was still loyal to ISIL's leader Abu Bakr al-Baghdadi.[263]

The group has since split into pro-Barnawi and pro-Shekau factions, with reports of armed clashes breaking out between them.[264] Shekau has released videos since the split in which he refers to his group by its previous name of Jamatu Ahlis Sunna Lidawatti wal Jihad.[265]

On 23 August, the Nigerian Army announced it conducted an overnight air-operation that was 'very successful' in killing the leadership of Boko Haram. Among those presumed killed was Abubakar Shekau, he died in an aerial bombardment in Taye village. The Nigerian Army claims that the disputed Boko Haram leader died from injuries to his shoulders while he was performing prayer.[266][267]

On 28 August, the Nigerian president Muhammadu Buhari, retracted the military's statement and claimed that the Boko Haram leader was 'wounded' but not killed in the air-strike.[268]

On 31 August, Major General Lucky Irabor stated that the militants now only controlled a few villages and towns near Lake Chad and in Sambisa Forest. He further stated that the military expected recapturing the final strongholds of the group within weeks.[269]

UNICEF reported an increase in child suicide bombers with 27 incidents occurring in the first three months of 2017 in Nigeria, Niger, Cameroon and Chad, compared to 30 in the entire previous year, 56 in 2015 and 4 in 2014. Kidnapped children who escape from Boko Haram are often held in custody or ostracized by their community or family. Patrick Rose, a UNICEF regional coordinator, stated: "They are held in military barracks, separated from their parents, without medical follow-up, without psychological support, without education, under conditions and for durations that are unknown". According to the NGO: "Society's rejection of these children, and their sense of isolation and desperation, could be making them more vulnerable to promises of martyrdom through acceptance of dangerous and deadly missions".[270][271] In addition to child suicide bombers and despite having been routed from key areas and significantly downgraded in their capacities, throughout 2016 and into 2017, Boko Haram in Nigeria continued to wage attacks against Nigerian security forces, the community-based Civilian Joint Task Forces (CJTF), and regular citizens, using improvised explosives devices (IEDs) and other crude weaponry. These were often deployed with suicide bombers; an increasing number of whom were women and girls recruited to attack markets, transportation depots, mosques, and IDP camps.[272]

On 22 March, suicide bombers bombed an IDP camp in the northeastern city of Maidiguri, killing four and wounding 18.[273]

Boko Haram kidnapped 110 schoolgirls from the Government Technical Girls College in Dapchi, Yobe State, on 19 February 2018. Boko Haram killed five of them on the same day. They released all but one of the surviving girls on 21 March, having been paid a large ransom by the Nigerian government to do so.[274][275][276]

On 2 April, a Boko Haram attack on the outskirts of Maiduguri resulted in the death of 18 people and another 84 wounded. This attack came just days after the government of Nigeria claimed there was a ceasefire with Boko Haram. The attack happened in the villages of Bale Shuwa and Bale Kura, close to both Maiduguri and the city's military camp.[277]

On 18 May, the Nigerian Army killed 15 Boko Haram insurgents and rescued 49 persons in separate encounters between Boko Haram and Nigerian troops throughout the Southern Lake Chad Basin. The Nigerian troops killed 11 of the insurgents during a battle in Gamoran Village, while the remaining insurgents were killed trying to escape from the Army's efforts in Northern Borno. The Nigerian troops rescued 4 men, 33 women, and 16 children from the insurgent's hideouts in the area.[278]

In December, Boko Haram launched a series of attacks in north-east Nigeria. Militants from Islamic State West Africa Province took over the town of Baga and seized the Multinational Joint Task Force base. The attacks took place two months prior to the presidential elections in Nigeria.[279]

On 23 March, Boko Haram fighters attacked soldiers in Boma, Chad, killing 92 and destroying 24 army vehicles. It marked the deadliest ever attack by Boko Haram on the country's military forces, and a serious escalation of conflict.[284] In its eight-day counter-operation "Operation Bohoma Anger", Chadian army claims to have killed around one thousand Boko Haram fighters while incurring 52 casualties of its own troops.[285][286] Of 58 suspected Boko Haram members, who had been captured during the operation, 44 died in a prison in N'Djamena mid-April 2020. The Minister of Justice Djimet Arabi stated that the men died as a result of poisoning.[287]

The Turkish ministry extended its sincere condolences to the families of those who lost their lives.[294]

On 24 December, 40 loggers were seized by the Boko Haram jihadists, while 3 others were killed in the Wulgo forest near the town of Gamboru in Nigeria. Bodies of three loggers were found in the forest by a militia leader, and the rest were presumed kidnapped.[295]

Boko Haram was founded by Mohammed Yusuf who led the group from 2002 until his death in 2009. After his death, his deputy Abubakar Shekau took control of the group and has led it until the present day.

Although Boko Haram is organized in a hierarchical structure with one overall leader, the group also operates as a clandestine cell system using a network structure,[296] with units having between 300 and 500 fighters each. Estimates of the total number of fighters range between 500 and 9,000.[297][298][299]

Boko Haram is said to have raised substantial sums from kidnap for ransom. In 2013, Boko Haram kidnapped a family of seven French tourists on vacation in Cameroon and two months later released the hostages along with 16 others in exchange for a ransom of $3.15 million.[300]

As well as extortion from local residents, Boko Haram has claimed to extort money from local state governments. A spokesman of Boko Haram claimed that Kano state governor Ibrahim Shekarau and Bauchi state governor Isa Yuguda had paid them monthly.[301]

It has long been alleged that Boko Haram had a relationship with al-Qaeda. In 2011, letters from Boko Haram were reportedly found in bin Laden's compound.[302]

Three weeks after the 2009 Boko Haram uprising began, al-Qaeda in the Islamic Maghreb expressed sympathy for Boko Haram.[303] Speaking by phone to reporters in November 2012, group spokesman Abu Qaqa said: "We are together with al-Qaeda, they are promoting the cause of Islam, just as we are doing. Therefore they help us in our struggle and we help them, too." The 2012 Reuters special report details how fighters have trained with al-Qaeda affiliates in small groups over at least 6 years.[92]

According to the UN Security Council listing of Boko Haram under the al-Qaeda sanctions regime in May 2014,[304] the group "has maintained a relationship with AQIM for training and material support purposes", and "gained valuable knowledge on the construction of improvised explosive devices from AQIM". The UN found that a "number of Boko Haram members fought alongside al Qaeda affiliated groups in Mali in 2012 and 2013 before returning to Nigeria with terrorist expertise". AQIM is one of al-Qaeda's regional branches, whose leader, Abu Musab Abdel Wadoud, has sworn an oath of allegiance to al-Qaeda's senior leadership.[305]

Despite historic ties, al-Qaeda central has never officially accepted Boko Haram as an affiliate. The issues between AQ and Boko Haram are related to the extremism of Abubakar Shekau with respect to him declaring the entire general population of Muslims in Nigeria to be non-Muslims. Shekau argues that due to the widespread apostasy of Muslims through voting in elections that it is legitimate to kill Muslim civilians. Al-Qaeda takes the view that the general population should be viewed as Muslim and thus killing civilians is not acceptable.[303][306]

In July 2014, Shekau released a 16-minute video where he voiced support for ISIL's head Abu Bakr al-Baghdadi, al-Qaeda's head Ayman al-Zawahiri and Afghan Taliban leader Mullah Omar.[307] In March 2015, Shekau formally pledged allegiance to ISIL, which was accepted by the group's spokesman several days later.[17] The group was nominally renamed 'Wilayat Garb Ifriqiyah' or the Islamic State's 'West African province' and was led by Shekau.

In August 2016, ISIL attempted to remove Shekau from his leadership role and replace him with Abu Musab al-Barnawi. The reason behind this was that Shekau had disobeyed Abu Bakr al-Baghdadi's order to cease targeting Muslim civilians. Shekau rejected the move, leading to a split between the groups.

In 2012, the U.S. Department of State had an internal debate on whether to place Boko Haram on its list of FTOs (Foreign Terrorist Organizations).[326] The Bureau of Counterterrorism leaned towards designation while the Bureau of African Affairs urged caution.[326] Officials from the Justice Department, the FBI, the CIA, and a number of members of Congress urged the State Department to designate Boko Haram as an FTO.[327] The Nigerian government voiced its opposition to an FTO designation, citing concerns that it would raise Boko Haram's stature and have implications for humanitarian aid in the region where Boko Haram operated.[326] Twenty academic experts on Nigeria signed a letter to the State Department urging it not to designate Boko Haram as an FTO, saying that it would hinder NGO efforts in the region and might legitimize the Nigerian Army's human rights abuses in its efforts to fight Boko Haram.[326][328][329]

The U.S. State Department designated Boko Haram and its offshoot Ansaru as terrorist organizations in November 2013, citing Boko Haram's links with AQIM and its responsibility for "thousands of deaths in northeast and central Nigeria over the last several years including targeted killings of civilians".[330] The State Department also cited Ansaru's 2013 kidnapping and execution of seven international construction workers.[330] In the statement it was noted, however, "These designations are an important and appropriate step, but only one tool in what must be a comprehensive approach by the Nigerian government to counter these groups through a combination of law enforcement, political, and development efforts."[330][331] The State Department had resisted earlier calls to designate Boko Haram as a terrorist group after the 2011 Abuja United Nations bombing.[332] The U.S. government does not believe Boko Haram is currently (2014) affiliated with al Qaeda Central, despite regular periodic pledges of support and solidarity from its leadership for al-Qaeda, but is particularly concerned about ties between Boko Haram and Al Qaeda in the Islamic Maghreb (AQIM) (including "likely sharing funds, training, and explosive materials").[47]

Efforts to cooperate in freeing the Chibok schoolgirls had faltered, largely due to mutual distrust; the infiltration of the military by Boko Haram meant that U.S. officials were wary of sharing raw intelligence data, and the Nigerian military had failed to supply information that might have aided U.S. drone flights in locating the kidnapped girls. The Nigerian government claims that Boko Haram is "the West Africa branch of the world-wide Al-Qaida movement" with connections to al-Shabaab in Somalia and AQIM in Mali. The Nigerian government denies having committed human rights abuses in the conflict, and therefore oppose U.S. restrictions on arms sales, which they see as being based on the U.S. mis-application of the Leahy Law due to concerns over human rights in Nigeria. The U.S. had supplied the Nigerian army with trucks and equipment but had blocked the sale of Cobra helicopters. In November 2014 the U.S. State department again refused to supply Cobras, citing concerns over the Nigerian military's ability to maintain and use them without endangering civilians.[333][334][335][336]

On 1 December 2014, the U.S. embassy in Abuja announced that the U.S. had discontinued training a Nigerian battalion at the request of the Nigerian government. A spokesman for the U.S. state department said: "We regret premature termination of this training, as it was to be the first in a larger planned project that would have trained additional units with the goal of helping the Nigerian Army build capacity to counter Boko Haram. The U.S. government will continue other aspects of the extensive bilateral security relationship, as well as all other assistance programs, with Nigeria. The U.S. government is committed to the long tradition of partnership with Nigeria and will continue to engage future requests for cooperation and training".[336]

On 24 September 2015, the White House announced a military aid package for African allies fighting Boko Haram. The package included up to $45 million for training and other support for Benin, Cameroon, Chad, Niger and Nigeria.[337] On 14 October, the White House released a statement, in accordance with the War Powers Resolution, announcing the deployment of 300 troops to Cameroon to conduct airborne ISR: "These forces are equipped with weapons for the purpose of providing their own force protection and security, and they will remain in Cameroon until their support is no longer needed."[338]

After a series of meetings over many months,[8][9][10] Cameroon's foreign minister announced on 30 November 2014 that a coalition force to fight terrorism, including Boko Haram, would soon be operational. The force would include 3,500 soldiers from Benin, Chad, Cameroon, Niger and Nigeria.[339][340] Discussions between the Economic Community of West African States (ECOWAS) about a broader based military force have been scheduled.[341]

France and the United Kingdom, in coordination with the United States, have sent trainers and material assistance to Nigeria to assist in the fight against Boko Haram.[342] France planned to use 3,000 troops in the region for counter-terrorism operations. Israel and Canada also pledged support.[343]

In 2017, the United Kingdom enforced an emergency assistance package worth $259 million. The United Kingdom has also aided Nigeria through military support and counter-terrorism training. The British government has provided training to 28,000 Nigerian military troops to aid the fight against Boko Haram. More than 40 British soldiers have also been sent on a long-term deployment to Nigeria.[344]

On 28 August 2018 the British government produced a press release describing the details the newly launched partnership between the United Kingdom and Nigeria which was formed to attempt to reduce the threat posed by Boko Haram to the citizens of the two nations. The press release gives an insight into the multiple methods (including community engagement and direct intervention by the Nigerian government) of preventing and reducing the impacts of attacks carried out by Boko Haram in Nigeria.

Specific details of the cooperation between the British and Nigerian governments include:

A £13 million programme to educate 100,000 children living in the conflict zone and; implementing a Nigerian crisis response mechanism to help the government respond to incidents like terror attacks and; cutting the number of new recruits joining Boko Haram by tackling the false information spread by the group to recruit new members.[345]

In May 2014, China offered Nigeria assistance that included satellite data, and possibly military equipment.[342]

In October 2015, Colombia sent a delegation of security experts to assist the Nigerian authorities and share expertise on security and counter terrorism.[346] In January 2016, a delegation led by Lieutenant General Tukur Yusuf Buratai also visited Colombia to exchange information in regards to the war against Boko Haram.[347][348]

In January 2019, when thousands of refugees from north-east Nigeria were forced to return from Cameroon, despite the continuous threat to civilian lives by Boko Haram jihadists, the United Nations was "extremely alarmed". "This action was totally unexpected and puts lives of thousands of refugees at risk," the United Nations High Commissioner for Refugees, Filippo Grandi said. The UNHCR appealed to Cameroon "to continue its open door and hospitable policy" and stop any more returns.[349]
